Wed Mar 16 2016: SModelS v1.0.4 is now available for download:

smodels-v1.0.4.tgz

If you use SModelS, please cite the quick guide (arXiv:1412.1745), the original SModelS paper (arXiv:1312.4175) as well as the tools used by the code: Pythia6.4, NLL-fast and PySLHA. For convenience a .bib file is provided with the code containing all relevant references. Likewise, a .bib file is provided in the database folder with references to all the ATLAS and CMS analyses used.


Introduction

SModelS is based on a general procedure to decompose Beyond the Standard Model (BSM) collider signatures presenting a Z2 symmetry into Simplified Model Spectrum (SMS) topologies. Our method provides a way to cast BSM predictions for the LHC in a model independent framework, which can be directly confronted with the relevant experimental constraints. Our concrete implementation currently focusses on supersymmetry searches with missing energy, for which a large variety of SMS results from ATLAS and CMS are available. The main ingredients are

  • the decomposition of the BSM spectrum into SMS topologies
  • a database of experimental SMS results
  • the interface between decomposition and results database (to check limits)

Known issues

  • The database.bib file is missing in v1.0.2 and v1.0.3.

  • In version <= v1.0.3: Temporary directories created while using the cross section computer (via script runTools.py) are not removed from the memory. They are empty as the contents are automatically deleted. Manually cleaning temporary directories is advised especially when running on a large number of points.

Code releases

Database updates

None right now, current release (v1.0.3) is included the latest version. See the release notes here.

SMS wishlist

A wishlist regarding the presentation of SMS results was worked out at the 2013 Les Houches workshop, see this page.
